SWISSCDC Standard
The Natural Buoyancy for Dry Flies
CDC (Cul de Canard) is one of the most valuable natural materials in modern fly tying. Harvested from the feathers surrounding a duck's preen gland, CDC naturally contains fine oils that work together with its unique fibre structure to provide exceptional buoyancy, subtle movement and an incredibly lifelike appearance on the water.
Unlike traditional rooster hackle, CDC allows flies to sit naturally in the surface film while trapping microscopic air bubbles within its fibres. This creates a highly realistic presentation that perfectly imitates emerging aquatic insects, making CDC indispensable for selective trout and grayling.
Today, CDC is used in countless proven fly patterns including the F-Fly, CDC Comparadun, CDC & Elk, Shuttlecock Emerger and Loop Wing Emerger. Its outstanding floating ability and natural movement have made it one of the most trusted fly tying materials available.
Premium Swiss CDC for Consistent Professional Results
SWISSCDC Standard represents the quality and consistency that have made Swiss CDC materials highly respected among fly tyers worldwide. Each pack contains a carefully selected assortment of feathers in various lengths, making it suitable for everything from tiny technical dry flies and emergers to larger mayflies, caddis patterns and other surface flies.
According to the manufacturer, only winter CDC feathers are selected, as feathers harvested during the winter season offer superior fibre structure and overall quality. Every batch is carefully cleaned, disinfected, sorted and dyed in small quantities to ensure excellent colour consistency and dependable performance.
The natural oils and exceptionally soft fibres create outstanding buoyancy while allowing flies to move naturally in the surface film. Whether you are tying classic patterns such as the F-Fly and CDC Comparadun or your own modern creations, SWISSCDC Standard delivers the versatility, consistency and premium quality expected from one of the world's leading CDC specialists.
